Critical behavior of interacting surfaces with tension
Wetting phenomena, molecular protrusions of lipid bilayers and membrane stacks under lateral tension provide physical examples for interacting surfaces with tension. Such surfaces are studied theoretically using functional renormalization and Monte Carlo simulations. The critical behavior arising from thermally–excited shape fluctuations is determined both for global quantities such as the mean...
متن کاملBacteria slingshot more on soft surfaces
Adaptive responses greatly improve the competitive capacities of bacteria in diverse environments. Here, we investigate whether bacteria can adapt to a microenvironment with distinctive softness by examining the type-IV pili (TFP)-mediated motility of Pseudomonas aeruginosa cells on brush-like surfaces that are grafted with a layer of thermally sensitive polymer chains, where the softness of th...

متن کاملDesigning surfaces that kill bacteria on contact.
Poly(4-vinyl-N-alkylpyridinium bromide) was covalently attached to glass slides to create a surface that kills airborne bacteria on contact. The antibacterial properties were assessed by spraying aqueous suspensions of bacterial cells on the surface, followed by air drying and counting the number of cells remaining viable (i.e., capable of growing colonies). Amino glass slides were acylated wit...
متن کاملSurvival of bacteria on metal surfaces.
Survivor curves were determined for Serratia marcescens, Sarcina lutea, Pasteurella tularensis, and P. pestis deposited from the airborne state onto metallic surfaces and subsequently stored at various humidities and temperatures. Cells of all species tested remained alive longest in a dry atmosphere, except that cells of S. marcescens survived best in a saturated atmosphere. Survival decreased...
